[0025] The mounting frame 1 is fixed in the console of the vehicle, then the extrusion block 3 at the bottom of the vehicle amplifier 101 is aligned with the guide slot 2 and pushed along the guide slot 2, when the extrusion block 3 contacts the inclined surface of the wedge block 4, the vehicle amplifier 101 is continuously pushed, the extrusion block 3 extrudes the wedge block 4, the wedge block 4 slides through the first guide rod 6 and compresses the first reset spring 5, when the extrusion block 3 completely passes through the wedge block 4, the first reset spring 5 rebounds and pushes the wedge block 4 to slide and reset, at this time, the right angle surface of the wedge block 4 contacts the right angle surface of the extrusion block 3, forming a locking state, thereby preventing the extrusion block 3 from sliding out of the guide slot 2, and when the extrusion block 3 extrudes the wedge block 4, the top block 13 is also extruded, the top block 13 slides through the third guide rod 14 and extrudes the second reset spring 15, because the extrusion block 3 cannot be pushed through the right angle surface of the wedge block 4 after passing through the wedge block 4, the vehicle amplifier 101 is installed and the second reset spring 15 is in a compressed state, when the vehicle amplifier 101 needs to be taken out, the operating rod 11 outside the mounting frame 1 is rotated, the operating rod 11 drives the threaded rod 8 to rotate through the bevel gear set 10, the threaded rod 8 pushes the push rod 7 to slide along the second guide rod 9, and simultaneously drives the wedge block 4 to move, the wedge block 4 compresses the first reset spring 5 in the sliding process, when the right angle surface of the wedge block 4 is separated from the extrusion block 3, the second reset spring 15 rebounds and pushes out the extrusion block 3 through the top block 13, thereby pushing out the vehicle amplifier 101, which is convenient for the user to take out the vehicle amplifier 101, when the operating rod 11 is rotated, the torsional spring 12 is twisted; when the vehicle amplifier 101 is popped out, the operating rod 11 is released, the rebounding force of the torsional spring 12 drives the operating rod 11 to rotate reversely, drives the threaded rod 8 to rotate reversely through the bevel gear set 10, thereby driving the push rod 7 which is connected with the threaded rod 8 to slide and reset along the second guide rod 9, and simultaneously driving the wedge block 4 to reset.

[0026] As shown in Figure 3 , further comprising a roller 16, the bottom of the extrusion block 3 is connected with the roller 16.

[0027] When the vehicle amplifier 101 is pushed in, the roller 16 at the bottom of the extrusion block 3 can reduce the friction when being pushed in, so that the vehicle amplifier 101 can be pushed in more easily, and at the same time, when the top block 13 pushes out the extrusion block 3, because of the existence of the roller, the extrusion block 3 can slide more smoothly, thereby popping out a sufficient distance, so that the user can directly take it by hand.

[0028] As shown in Figure 2 , further comprising a sealing plug 17, the opening of the guide slot 2 is connected with the sealing plug 17 on the mounting frame 1, the sealing plug 17 is extruded and matched with the guide slot 2, the opening of the guide slot 2 is provided with a rounded corner to the left and right sides and is provided with an arc surface 18.

[0029] The arc surface 18 is arranged at the opening of the guide slot 2, which facilitates the alignment of the extrusion block 3 with the guide slot 2, and the sealing plug 17 can ensure the cleanliness of the guide slot 2 and the stability of the extrusion block 3 during movement, so that the extrusion block 3 will not be stuck due to the entry of foreign matters.

[0030] As shown in Figure 1 The convex block 19 is connected to the part of the operating rod 11 extending out of the outer frame 1.

[0031] The convex block 19 makes the surface of the operating rod 11 rougher, so that the rotation process is more stable when the operating rod 11 is rotated.

[0032] The outer frame 1 is fixed in the vehicle console, the car audio amplifier 101 is connected with the guide slot 2 in the outer frame 1 through the extrusion block 3 at the bottom of the car audio amplifier 101, the roller 16 at the bottom of the extrusion block 3 reduces the friction when the car audio amplifier 101 is pushed in, the round corner at the opening of the guide slot 2 and the sealing plug 17 facilitate the alignment of the extrusion block 3 with the guide slot 2 and keep the cleanliness of the guide slot 2. During the pushing-in process, the extrusion block 3 first contacts the inclined surface of the wedge block 4, pushes the wedge block 4 to slide and compress the first return spring 5. Once the extrusion block 3 completely passes through the inclined surface of the wedge block 4, the first return spring 5 immediately rebounds, pushes the wedge block 4 to slide and reset, at this time, the extrusion block 3 contacts the right-angle surface of the wedge block 4, and a locking state is formed to prevent the car audio amplifier 101 from sliding out. Meanwhile, the extrusion block 3 also extrudes the top block 13 during the pushing-in process, so that the top block 13 slides through the third guide rod 14 and compresses the second return spring 15. When the car audio amplifier 101 needs to be taken out, the operating rod 11 is rotated, the threaded rod 8 is driven to rotate through the bevel gear set 10, and then the push rod 7 is pushed to slide along the second guide rod 9, the push rod 7 extrudes the wedge block 4 to move and compress the first return spring 5 again. When the right-angle surface of the wedge block 4 is separated from the extrusion block 3, the second return spring 15 rebounds, pushes the extrusion block 3 and the car audio amplifier 101 out through the top block 13, so that the user can easily take out the car audio amplifier 101. During the rotation process of the operating rod 11, the torsional spring 12 is twisted, and after the car audio amplifier 101 is popped out, the operating rod 11 is released, the reverse torsional force of the torsional spring 12 drives the operating rod 11 to rotate reversely, the threaded rod 8 is reversely rotated through the bevel gear set 10, and the push rod 7 is reset, and at the same time, the first return spring 5 also pushes the wedge block 4 to reset.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the present application.
